Serial Killer: "an individual who murders three or more people, usually due to abnormal psychological gratification, with the murders taking place over more than a month and including a significant break (a "cooling off period") between them."
Human: "of, relating to, or characteristic of people or human beings"; thus homo sapiens.
How many seriel killers have not been homo sapiens? Nada
They are definitely human, Yes, But the general public does not consider them as such. Humans tend to distance themselves from terrible things, So one such way of doing that is to label serial killers as monsters, Witches, And other inhumane creatures. The media helps greatly with that by exaggerating details and through the use of certain words describing them. So in conclusion, Serial killers are human but the public does not see them as such.
